I have been following the guides and posts here on the site but can not seem to get my phone to register externally. It will via wifi internally. I have had it work before via vpn, but would rather a direct connection as the vpn often drops and then the phone will also.

I can get the phone to register, but the person I call from the iphone can hear me. I can not hear them. Works fine internally but not externally (3g). I have tried the 3cx app and Bria, both do the same thing. When connected internally via wifi works fine? Any suggestions?

sounds like you have a nat issue and dont have ports UDP 9000 thru 9049 forwared from the router to the 3cx system. remember when the 3cx app is started outside the network it uses different rtp ports then inside the network.

the rtp ports should be udp only. also make sure that no other services on the router are using those ports. It may be useful to have have the pbx delvier audio activated on the 3cx console for the extension.
